    Description

      We have a persistent buildbot failure:
      http://buildbot.askmonty.org/buildbot/builders/kvm-rpm-centos5-amd64/builds/1981/steps/test/logs/stdio

      It is reproducible on a child of the same VM (or of the sibling -build VM).
      If I build server exactly as the buildbot test does, and install the resulting RPM file, I get the same problem: on an attempt to set wsrep_provider the server complains

      and immediately crashes:

      [ERROR] mysqld got signal 6 ;
      ...
      Thread pointer: 0x0x77e0270
      Attempting backtrace. You can use the following information to find out
      where mysqld died. If you see no messages after this, something went
      terribly wrong...

      Trying to get some variables.
      Some pointers may be invalid and cause the dump to abort.
      Query (0x7879368): set global wsrep_provider="/usr/lib64/galera/libgalera_smm.so"
       
      Connection ID (thread ID): 1
      Status: NOT_KILLED

      But if I take mysqld binary from the same build and put it into /usr/sbin/ instead of the installed mysqld, there are no complaints about IP search, and no crash.
